Ernest Frederick II

Ernst Frederick II, Duke of Saxe-Hildburghausen (b. Hildburghausen, 17 December 1707 - d. Hildburghausen, 13 August 1745), was a duke of Saxe-Hildburghausen.

He was the third but eldest surviving son of Ernst Frederick I, Duke of Saxe-Hildburghausen and Sofie Albertine of Erbach-Erbach.

He succeded to his father in the duchy of Saxe-Hildburghausen with only seventeen years old (1724); because of this, his mother, the Dowager Duchess Sofie Albertine, acted as a regent on behalf of his son until he reached adulthood, in 1727.

In Fürstenau on 19 June 1726 Ernst Frederick married with Caroline of Erbach-Fürstenau. They have four children:

1. Ernst Frederick III Karl, Duke of Saxe-Hildburghausen (b. Königsberg, 10 June 1727 - d. Seidingstadt, 23 September 1780).
2. Frederick August Albrecht (b. Hildburghausen, 8 August 1728 - d. Hildburghausen, 14 June 1735).
3. Frederick Wilhelm Eugen (b. Hildburghausen, 8 October 1730 - d. Öhringen, 4December 1795), married on 13 March 1778 to his niece Caroline of Saxe-Hildburghausen (daughter of Ernst Frederick III). Their marriage was childless.
4. Sophie Amalie Caroline (b. Hildburghausen, 21 July 1732 - d. Öhringen, 19 June 1799), married on 1749 to Ludwig of Hohenlohe-Oehringen.
